Question

question 2. examine picture b. then, identify whether the organism is symmetrical or asymmetrical. if it is symmetrical, determine whether it has bilateral or radial symmetry. finally, state which animal phylum you would classify the organism in.

Explanation:

To solve this problem, we would typically analyze the organism in Picture B (which is not provided here). However, since the image of the organism is missing, we can't directly classify it. Here's a general approach for such a problem:

Step 1: Analyze Symmetry

• Asymmetrical: If the organism has no plane of symmetry (e.g., some sponges).
• Symmetrical: If there is at least one plane of symmetry. Then, determine if it's bilateral (one plane dividing into mirror - image halves, e.g., humans) or radial (multiple planes around a central axis, e.g., jellyfish).

Step 2: Classify Phylum

• Use the symmetry and other characteristics (like body structure, presence of a coelom, segmentation, etc.) to classify the organism into a phylum. For example:
• Porifera (Sponges): Often asymmetrical or have radial symmetry, simple body structure with pores.
• Cnidaria (Jellyfish, Corals): Radial symmetry, have stinging cells (cnidocytes).
• Platyhelminthes (Flatworms): Bilateral symmetry, flattened body, acoelomate.
• Annelida (Earthworms): Bilateral symmetry, segmented body, coelomate.
• Arthropoda (Insects, Spiders): Bilateral symmetry, exoskeleton, segmented body, jointed appendages.
• Mollusca (Snails, Octopuses): Bilateral symmetry (some secondarily radial), soft body, often with a shell.
• Echinodermata (Starfish, Sea Urchins): Adults have radial symmetry (larvae bilateral), endoskeleton, water - vascular system.
• Chordata (Vertebrates, Tunicates): Bilateral symmetry, notochord (at some stage), dorsal nerve cord, pharyngeal slits.

Since the picture of the organism (Picture B) is not provided, we can't give a specific answer about its symmetry and phylum classification. If you can provide a description or the image of Picture B, we can proceed with the analysis.
